  • said circuit blocks 40 , 50 can be made on the same printed circuit board or, as in the depicted example in the figures, they can be made on different circuit boards 43 , 51 and be electrically connected to each other for example by means of a connector 49 and a multipolar cable 59 .
  • the second circuit block 50 comprises a circuit board 51 being fastened to the cells 30 by means of screws 55 that are mounted in respective seats 35 provided for in the support device 31 of the cells 30 .
  • Both the above-mentioned circuit blocks 40 , 50 can be powered directly or indirectly by the cells 30 .
  • the two circuit blocks 40 , 50 are separated:
  • the rechargeable battery pack 20 comprises one or more electrical connectors 23 (in the example three connectors 23 ) in the connection portion 23 allowing electrically connecting the rechargeable battery pack 20 and, in the specific and non-limiting case, the second circuit block 50 , with the powertrain group 5 .
  • at least one of said connectors 23 is needed to connect the first circuit block 40 with the dashboard 10 (if provided for), via the second circuit block 50 .
  • the above-mentioned electrical connectors 23 represent at least one electrical connection element of the rechargeable battery pack 20 with the powertrain group 5 .
  • the proposed rechargeable battery pack 20 allows fully obtaining the intended objects in terms of overcoming the drawbacks of the known art.
  • that rechargeable battery pack 20 represents an effective solution being adapted to prevent and/or discourage the thefts or to promptly signal the occurrence of a theft.
